Question 9 (15 marks) consider the integral where f = (3y,_xz,_yz2) and where s is the portion of the surface 2z = z2-+ u2 below the plane ? 2. (a) calculate the given integral directly using cylindrical coordinates (b) now calculate the given integral using stokes' theorem. question 10 (10 marks) (a) let s be the solid determined by 1 x2 + y2 +z2-4 and let f-# zi + (2y + z)j + (z + 2.2)k. evaluate f ds. as (b) let w be a solid in r3 with surface boundary ow, and let f be a scalar field in r3. prove that ow

Jabari is power washing houses for a summer job. for every job, he charges an initial fee plus $30 for each hour of work. his total fee for a 4 -hour job, for instance, is $170 . jabari's total fee,f, for a single job is a function of the number,t, of hours it takes him to complete the job. write the function's formula.

Me! i'm really confused the isosceles trapezoids, abcd and efgh, are similar quadrilaterals. the scale factor between the trapezoids is 2: 3, line gh = 6 centimeters, line ad = 8 centimeters, and line ab is three times the length of line dc . use complete sentences to answer the following prompts and include all of your calculations in your final answer. a. write a similarity statement for each of the four pair of corresponding sides. b. write a congruence statement for each of the four pair of corresponding angles. c. determine the perimeter for each of the isosceles trapezoids.
